Grinding noise

The black "stuff" could be the inside of the pulley coming apart.

On the part where the belt is gripping the pulley?

Yes, it can happen, but that also could be left over from the old belt. Best if you post pics here of what you are seeing.

it can happen from wear or if the pulley is a tiny hair out of spec maybe if it does it's usually just from a outer edge of the belt, my alternator pulley has done that before if it is a lot it might be a concern but it's just a tiny bit I wouldn't worry about it.
like stated post some pics and we can help make a determination, you just click on the photo frame above to the right of the chain links

Here’s a video I was waiting for it to upload.

Idler pulley

Hey guys I changed my pulley. Now I’m thinking I did something wrong. Belt doesn’t seem to sit all the way on the new idler pulley. Did they give me the wrong one? It looks different than the factory one. It’s a durlast. Seems to sit just a hair off. Click this link

Update: there was a spacer behind the pulley that was making it stick out just a hair to far… (the spacer, screw and mount were from the old pulley)
I removed the spacer and reinstalled the new pulley and now the belt sits correctly on the pulley with no over hang.

Edit: Here’s what I did

Is the spacer needed?

So long as the bearing spins freely, I would say NO. I looked at my old bearing, and it had a much thicker spacer. Probably goes with whatever bearing they decided to use in the pulley.

That build up on the pulley surface is nothing to worry about. You are fine.

I drove around all day today no issues. No overheating. It does spin freely.
